- India has 89 Ramsar sites (as of March 2025), covering mangroves, lakes, estuaries, coral reefs.
- Ramsar sites aid biodiversity conservation, climate regulation, and water management.
Ramsar Convention
- International treaty for wetland conservation, signed 1971 in Ramsar, Iran; in force since 1975.
- India joined in 1982;
- World Wetlands Day: 2 Feb.
- 3 Main Objectives:
- Identify & protect wetlands of international importance.
- Promote wise use of wetlands.
- Encourage international cooperation.
- Wise Use: Sustainable management balancing conservation & livelihoods.
Nine Ramsar Criteria for Identifying Wetlands of International Importance
The Ramsar Convention uses nine scientific criteria, grouped under two categories, to designate wetlands of international importance:
Group A – Sites containing representative, rare, or unique wetland types
- Criterion 1 – Representative, Rare, or Unique Wetland Types
- The site should contain a natural or near-natural wetland type that is rare, unique, or representative of the region’s ecological or biogeographic setting.
- Examples:
- Chilika Lake, Odisha – largest brackish lagoon in Asia, unique salinity gradient.
- Sundarbans, West Bengal – world’s largest contiguous mangrove forest.
Group B – Sites of international importance for conserving biological diversity
- Criterion 2 – Threatened Species & Ecological Communities
- Supports vulnerable, endangered, or critically endangered species or threatened ecological communities.
- Example: Keoladeo National Park – habitat for the critically endangered Siberian Crane.
- Criterion 3 – Biodiversity Support
- Maintains biodiversity of the region by supporting populations of plant and/or animal species important for the region’s biological balance.
- Example: Loktak Lake, Manipur – floating “phumdis” support unique flora and fauna.
- Criterion 4 – Critical Life Cycle Support
- Provides habitat during critical life stages (breeding, nesting, moulting, migration stopover) or as a refuge during adverse conditions.
- Example: Pong Dam Lake, Himachal Pradesh – stopover for thousands of migratory waterfowl.
- Criterion 5 – Waterbird Aggregations
- Regularly supports 20,000 or more waterbirds.
- Example: Chilika Lake – over 1 million migratory birds annually.
- Criterion 6 – Specific Waterbird Populations
- Regularly supports ≥1% of the individuals in a population of one species/subspecies of waterbird.
- Example: Nal Sarovar, Gujarat – >1% of the global population of certain duck species.
- Criterion 7 – Fish Diversity & Life Stages
- Supports a significant proportion of indigenous fish subspecies, species, or families, or important fish spawning/nursery grounds.
- Example: Ashtamudi Lake, Kerala – vital for clams and diverse fish species.
- Criterion 8 – Fish Source for Food/Spawning
- An important source of food for fishes, spawning grounds, nursery areas, or migration paths on which fish stocks depend.
- Example: Deepor Beel, Assam – fish breeding and feeding grounds for Brahmaputra River system.
- Criterion 9 – Non-Avian Species Populations
- Regularly supports ≥1% of the individuals in a population of one species/subspecies of wetland-dependent non-avian animals (e.g., amphibians, mammals, reptiles).
- Example: Vembanad-Kol Wetland, Kerala – supports endangered Irrawaddy dolphins.
New Ramsar Sites (Dec 2024)
- Ankasamudra Bird Conservation Reserve (Karnataka) – Freshwater wetland; key for migratory birds, flood buffer, fisheries support.
- Aghanashini Estuary (Karnataka) – Mangrove-rich estuary; breeding ground for marine species; coastal protection.
- Magadi Kere Conservation Reserve (Karnataka) – Seasonal freshwater lake; Sarus Crane breeding site; groundwater recharge.
- Karaivetti Bird Sanctuary (Tamil Nadu) – Migratory bird stopover on EAAF; supports fishing communities.
- Longwood Shola Reserve Forest (Tamil Nadu) – Montane wetland forest; endemic fauna; water source for Nilgiris.
New Ramsar Sites (Feb 2025)
- Udhwa Lake Bird Sanctuary (Jharkhand) – First Ramsar site in state; vital for migratory birds & fisheries.
- Khecheopalri Wetland (Sikkim) – High-altitude sacred lake; endemic species; key freshwater source.
- Sakkarakottai Bird Sanctuary (Tamil Nadu) – Brackish wetland; migratory bird hub; flood control.
- Therthangal Bird Sanctuary (Tamil Nadu) – Seasonal freshwater wetland; supports groundwater recharge.
Importance of New Sites – Strengthen wetland conservation, enhance biodiversity protection, support eco-tourism, meet SDG & Paris Agreement goals, improve climate resilience.
Major Threats to Wetlands in India
- Urbanization & encroachment – loss of biodiversity, reduced flood control.
- Pollution – eutrophication, microplastics, water contamination.
- Climate change – salinity shifts, habitat drying, migration disruption.
- Invasive species – oxygen depletion, native species decline.
- Overexploitation – unsustainable fishing/tourism, poaching.
Government Initiatives
- NPCA – National Plan for Conservation of Aquatic Ecosystems.
- Wetlands Rules 2017 – prohibits encroachment/conversion.
- NAFCC – funds climate-resilient wetland projects.
- Mangrove & Coral Reef Programme – restoration efforts.
- ESZ Policy – buffer zones for wetland protection.
Conclusion
- With 89 Ramsar sites, India leads South Asia in wetland recognition.
- Stronger enforcement, community participation, and scientific management are key to long-term sustainability.
